The musical features a score by Frank Loesser with a book by Abe Burrows, Jack Weinstock and Willie Gilbert.

The original 1961 production earned seven Tony Awards, including Best Musical, Best Author and Best Score, as well as the Pulitzer Prize for Drama. Robert Morse earned a Tony Award for his performance as J. Pierrepont Finch. How to Succeed was last revived on Broadway in 1995 starring Tony winner Matthew Broderick and Megan Mullally.
